METAL TUG FOR HARNESS.

SPECIFICATION forming part of Letters Patent No. 439,682, dated November4, 1890. Application filed July 24, 1890- Serial No. 359,759. (Nomodel.)

To all whom it may concern:

Be it known that I, JOHN T. POHLMAN, a citizen of the United States,residing at New Haven, in the county of New Haven, in the State ofConnecticut, have invented a new and useful Metal Tug for Harnesses, ofwhich the following is a specification.

The object of my invention is to provide a metal tug for harnesses of asimple and ornamental design, adapted to be readily attach ed to ordisconnected from the harness-saddle and by pivotal connectionstherewith to permit the vibration of the shafts without oscillation ofthe saddle and consequent chafing of the back of the horse.

The invention consists in the novel arrangement and combination of ametal supporting-strap, having the slotted pivot-socket, and the metaltug, having the T or toggle pivot adapted thereto, as hereinafter morefully described and claimed.

In the accompanying drawings, forming a part of this specification,Figure l is a side view of myimproved tug and supporting-strap asconnected in operation. Fig. 2 is a front elevation of Fig. 1, viewedfrom the side next to the horse when in use. Fig. 3 is an end view ofthe supporting-strap shown in Figs. 1 and 2. Figs. 4 and 5 are views ofthe supporting-strap and tug, illustrating the mode of attaching orconnecting the said parts.

Referring to the drawings, A designates my improved tug, which is formedof malleable iron, brass, or other suitable metal, having the ordinarycircular or elliptical opening B to admit the shafts of the vehicle. Onthe lower side of the tug A is a suitable depending eye l-l, formedintegral therewith, for the attachment of the ordinary shaft-girt C. Onthe upper side of the tug A, and formed integrally therewith, is avertical neck or shank D, provided at the upper end with oppositelateral trunnions e e, extending parallel with the shaft-opening B andforming with the said neck D a T-shaped toggle-head n. Thesupporting-strap F is formed of malleable iron, brass, or other suitablemetal, and is of the same width as the tug A. In the lower part thereofis an opening or chamber g, extending through it in the direction of itswidth, as shown. The width of said opening 9 corresponds to the diameterof the trunnions, and

the height of the said opening or chamber or its dimensions lengthwiseof the supportingstrap corresponds to the length of the togglehead n.Centrally on one side of the supporting-strap F is a vertical slot K,communicating with said chamber g, extending. from the lower end of thestrap to the upper side of the opening g and corresponding in width tothe diameter of the trunnion. Said slot is adapted to admit thetoggle-head or trunnions into the opening g, as shown in Fig. 4:, andthe said opening 9 is adapted to permit the said toggle-head to turntherein through a quarterrevolution as the tug A is turned from theposition shown in Fig. 4 to that shown in Fig. 5, which will bring saidtoggle-head at right angles to the slot K, as shown" in said Fig. 5, andthe toggle-head and trunnions will thus be toggled in thesupporting-strap F. The lower side of said opening is made circular toreceive and form bearings for the said trunnions e e,which, after thetug is turned to the position shown in Fig. 5, may be dropped down intosaid bearings, and the tug may then be swung 011 said trunnions down tothe position shown in Fig.1, the slot K permitting the neck or shank Dto swing, as described. The opposite side of the strap is slotted up alittle way from the bottom to form a clearancespace m for the said shankto swing in when the tug is oscillated past a vertical plane lengthwisethrough the strap F. The upper part of the strap F has two rectangularapertures r- 1" formed therein, separated by a cross-bridge u, having aspur t at the back thereof, thus providing for the attachment of thesaddle-strap,which may be passed through the apertures with the spurpenetrating it, thus holding it in place. strap Fis fastened to thesaddle-girt with the slot K toward the horse, and in operation the tugcannot be detached therefrom, except by being swung into a horizontalposition toward the horse and then revolved aquarter-tnrn to a positionshown in Fig. 4. The strap and the trunnions of the toggle-head form ahinged joint,which permits the shafts to swing without oscillating thesaddle upon the back of the horse. By the peculiar construction of thetoggle-head and trunnions and the strap having its pivot-chamber gadapted thereto the parts when attached are hinged together Saidsupportingwithout involving the use of a rivet or pivot-al piece.

The parts are simple in construction and can be readily polished,plated, and connected together, and may be cheaply and convenientlyapplied to harnesses old or new, and is of neat and ornamental design.

Having fully described my invention, what I desire to claim and secureby Letters Patent, 1&-

1. The combination of the metal tug provided on its upper side with avertical neck or shank havinglateral trunnions in the plane of theshaft-opening forming a T-shaped togglehead, and the metalsupporting-strap adapted for attachment to the harness-saddle formedwith an opening or chamber in its lower part, having a central verticalslot opening fhereinto at the side and bottom thereof, adapted to admitthe toggle-head of the tug into said chamber, the chamber correspondingto the said head and permitting the quarterturn thereof, having bearingsat its lower side to support the toggle-trunnions,whereby they areretained in engagement with and hinged to the supporting-strap, asspecified.

2. The combination of the metal tug provided on its upper side with avertical neck or shank having lateral trunnions in the plane of theshaft-opening forming a T-shaped toggle-head, and the metalsupporting-strap having eyes or apertures in its upperpart forattachment to the harness-saddle formed with an opening or chamber g inits lower part, having the central vertical slot K opening thereinto atthe side and bottom thereof, adapted to admit the toggle-head of the tuginto said chamber, the chamber corresponding to the said head andpermitting the quarter-turn thereof, and having bearings at its lowerside to support the toggled trnnnions, whereby they are retained inengagement with and hinged to the strap, as specified.
